Maintenance is crucial for the long term health and operation of green roofs, walls and facades.SONY DSC


A detailed maintenance plan will outline performance standards, tasks to be undertaken and the resources required to achieve them. Once created, maintenance plans should be reviewed at least annually to ensure all maintenance needs are being met.

Maintenance plans must ensure that the vegetation present on a green roof, wall or facade does not create fire hazards. Dead or dry vegetation must be removed as part of regular maintenance. Fire resistance can be increased by installing breaks in the vegetation or using plants with low biomass (such as native grass tussocks with a low amount of leaf matter). Green facades with deciduous or evergreen climbers are unlikely to create a fire risk as long as dry leaf litter falls away cleanly and is removed during routine maintenance. Vegetation on green walls that receives regular irrigation and maintenance does not pose a fire hazard.
